Flail Chest-I01:24

Flail Chest-I

Overview of Flail Chest
Flail chest is a severe and potentially life-threatening condition characterized by the fracture of three or more adjacent ribs in multiple places. It is most commonly caused by direct impacts and trauma, such as motor vehicle accidents or injuries from a steering wheel impact. It can also occur due to falls in elderly individuals with osteoporosis, or assaults involving sharp objects.
Pathophysiology
The pathophysiology of flail chest is complex, involving fractures of...

Bones of the Upper Limb: Radius01:09

Bones of the Upper Limb: Radius

2.5K
The radius is longer of the two bones that make up the human antebrachium or forearm. At the proximal end, the radius articulates with the capitulum of the humerus and the radial notch of the ulna to form the elbow joint. At the distal end, the radius articulates with the ulna via the ulnar notch, forming the distal radioulnar joint. Distally, the radius also attaches to the carpal wrist bones (scaphoid and lunate) to form the radiocarpal joint.
The radius has a nail-shaped head, and a...

Flail Chest-II

Managing flail chest, a condition characterized by a segment of the chest wall moving independently from the rest of the thoracic cage, requires a comprehensive approach. It includes a thorough assessment of the patient's condition, a diagnostic evaluation to determine the extent of the injury, and the implementation of appropriate medical interventions tailored to the individual's needs.

Fractures: Bone Repair01:27

Fractures: Bone Repair

3.6K
Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...

Bones of the Upper Limb: Humerus01:19

Bones of the Upper Limb: Humerus

4.0K
The upper limb consists of the arm, forearm, wrist, and hand bones. The humerus is the single bone of the upper arm region. Proximally, it has a large, spherical, smooth head that articulates with the glenoid cavity of the scapula to form the glenohumeral or shoulder joint. The margin of the head is the anatomical neck, a residual epiphyseal plate. Laterally it extends to form bony projections called the greater tubercle and the lesser tubercle. Next to the tubercles is the surgical neck, a...

Bones of the Upper Limb: Ulna01:15

Bones of the Upper Limb: Ulna

2.5K
The ulna and radius are parallel bones of the antebrachium or the forearm. The ulna lies medially and consists of a bony tip called the olecranon process at its proximal end. This hook-like projection articulates with the olecranon fossa of the humerus and forms the "hinged" ulnohumeral part of the elbow joint. This joint facilitates forearm extension and flexion while preventing its hyperextension. Similarly, the coronoid process, another bony projection on the proximal/anterior side...

Area of Science:

  • Orthopedic Surgery
  • Emergency Medicine
  • Radiology

Background:

  • Wrist pain is a common emergency department complaint.
  • Triquetrum fractures are relatively uncommon wrist injuries.
  • Pisiform dislocation is a rare associated injury.

Observation:

  • A patient presented with isolated wrist pain.
  • Plain radiography revealed a minimally displaced triquetrum avulsion fracture.
  • Subtle dislocation of the pisiform bone was also identified.

Findings:

  • The diagnosis combined a triquetrum fracture with a concurrent pisiform dislocation.
  • This specific combination of injuries is infrequently reported in medical literature.

Implications:

  • Highlights the importance of thorough wrist examination in the emergency setting.
  • Underscores the need for advanced imaging or careful review when suspecting rare carpal bone injuries.
  • Informs orthopedic management strategies for complex wrist trauma.
